How to register a drone on Digital Sky: the eGCA UIN walkthrough

Drone registration on Digital Sky shifted to the eGCA framework after the DGCA migrated multiple drone services between 4 July 2025 and 15 July 2025 (DGCA Migration Notice, 3 July 2025). The transition changed the application flow, introduced Form D-2 as the primary UIN application mechanism, and connected Bharatkosh directly to the payment process. The Digital Sky platform now handles airspace permissions and NPNT, while DGCA drone registration runs through the eGCA portal. Operators registering unmanned aircraft systems under the Drone Rules 2021 now complete identity verification, drone profile creation, and UIN issuance through eGCA before seeking NPNT-based flight permissions on DigitalSky. The fee is ₹100, and the UIN remains permanent for the airframe under Rule 46 of the Drone Rules 2021.

The Digital Sky to eGCA migration: what changed in July 2025

India's civil drone framework entered a second operational phase after the Directorate General of Civil Aviation migrated drone services from the legacy Digital Sky workflow to the eGCA ecosystem in July 2025 (DGCA Public Notice, 3 July 2025). The first migration wave moved Type Certificate services under Form D-1 on 4 July 2025. The second wave transferred UIN issuance, transfer, de-registration, and Remote Pilot Certificate generation through Forms D-2, D-3, and D-4 on 15 July 2025 (DGCA Public Notice, 15 July 2025).

The eGCA (e-Governance for Civil Aviation) portal, built by Tata Consultancy Services on the TCS DigiGOV platform, now offers 298 aviation services including drone registration online India. The platform consolidates licensing, certification, and regulatory approvals across 12 DGCA directorates into a single applicant interface. Officially the airspace platform is written as DigitalSky in Ministry of Civil Aviation notifications, though most operators search for it as the Digital Sky platform.

The migration created confusion because DigitalSky did not disappear entirely. Airspace permission requests, NPNT permission artefacts, and map-based operational approvals continue on the DigitalSky stack. Registration and licensing functions, however, moved to the eGCA portal under the DGCA DigiGov architecture. The difference between eGCA and DigitalSky now defines how operators manage compliance: eGCA handles identity, aircraft, and pilot records, while DigitalSky handles airspace and flight permissions. Operators now access drone registration services through the DGCA applicant portal hosted at dgca.gov.in/digigov-portal instead of the older digitalsky.dgca.gov.in registration flow (Ministry of Civil Aviation, 15 July 2025).

The change also aligned drone governance with the Bharatiya Vayuyan Adhiniyam 2024, which came into force on 1 January 2025 and replaced the ninety-year-old Aircraft Act 1934 (Bharatiya Vayuyan Adhiniyam 2024, Gazette Notification S.O. 5646(E), 31 December 2024). Under the updated process, every eligible unmanned aircraft system requires a Unique Identification Number before operational deployment unless it falls under a defined exemption category in Rule 5 of the Drone Rules 2021. Operators managing agricultural spraying platforms, survey drones, inspection UAVs, logistics aircraft, or training fleets now need a working understanding of both eGCA registration and DigitalSky flight permissions.

Registration eligibility and exemptions under Rule 5

Drone registration eligibility under the Drone Rules 2021 depends on the aircraft category, operational purpose, and maximum all-up weight. India's framework treats "unmanned aircraft system" (UAS) and "remotely piloted aircraft system" (RPAS) as interchangeable terms under Rule 3 of the Drone Rules 2021. The framework classifies drones into Nano, Micro, Small, Medium, and Large categories using MAUW thresholds defined under Rule 5. The full mapping appears in the drone categories by weight cluster, which sits alongside this walkthrough inside the Kodainya regulatory corpus.

Nano drones remain exempt from registration only when they operate below the speed and altitude thresholds set in Rule 5 of the Drone Rules 2021. Once operations exceed those thresholds or involve commercial deployment, the nano drone registration exemption under Rule 5 no longer applies, and Form D-2 registration becomes mandatory.

Research and development exemptions also exist under Rule 9 for authorised government entities, recognised educational institutions, and notified testing organisations operating inside approved testing zones (Drone Rules 2021, Rule 9). Those exemptions apply narrowly and do not replace operational permissions where required.

Unregistered drone operation above the Nano threshold attracts penalties under the enforcement provisions of the Bharatiya Vayuyan Adhiniyam 2024, including fines and possible airframe seizure. Imported drones require additional scrutiny because operators must establish lawful import documentation before initiating UIN issuance. The DGCA also validates type certification details and radio-frequency approvals during imported drone registration workflows.

Operators seeking operational permissions after registration should also understand the relationship between UIN issuance and the NPNT permission layer described in NPNT and the permission artefact and the Indian drone airspace zone map.

Documents required for the Form D-2 application

The eGCA workflow begins with identity verification and drone-profile documentation. Applicants submitting Form D-2 for a Unique Identification Number must provide identity documents, ownership records, and aircraft details before payment processing starts.

The Drone Amendment Rules 2023 expanded accepted identity documents for drone registration applicants. Operators can now use Aadhaar, Passport, PAN, Driving Licence, or Voter ID during e-KYC verification (Drone Amendment Rules 2023, 27 September 2023). Aadhaar drone registration through e-KYC remains the most common identity path, though the expanded 2023 document list gives operators four alternatives where Aadhaar verification fails. Earlier workflows relied primarily on Aadhaar-linked onboarding, which created friction for enterprise operators managing distributed pilot teams across states.

Applicants also need the drone serial number, manufacturer details, model designation, maximum all-up weight classification, and the corresponding DGCA Type Certificate drone India number where applicable. Imported aircraft require Directorate General of Foreign Trade import authorisation details and Wireless Planning & Coordination Wing radio-frequency approvals for compliant communications hardware (DGFT Notification, 9 February 2022).

The DGCA validates ownership consistency between the applicant identity and the aircraft documentation. Serial-number duplication remains one of the common rejection reasons during manual review. Operators purchasing second-hand drones should verify that the previous owner completed de-registration under Form D-3 before starting a fresh application.

The eGCA system also requires applicants to select the correct profile type during onboarding. Individual operators, organisations, manufacturers, importers, and training institutions each use separate profile categories linked to different compliance obligations.

Operators working through the complete drone laws in India guide or the type certification for Indian drones framework should complete those checks before starting Form D-2 submission. Once documents are ready, the seven-step Form D-2 workflow begins on the eGCA portal.

The seven-step eGCA UIN walkthrough using Form D-2

The DGCA drone registration workflow now starts on eGCA at dgca.gov.in/digigov-portal — not the legacy digitalsky.dgca.gov.in URL that competitor articles still cite. The process links identity verification, aircraft registration, payment processing, and UIN issuance inside one application chain. Each step has a specific failure pattern operators should understand before they start.

The first step involves account creation on the DGCA DigiGov portal at dgca.gov.in/digigov-portal. Applicants complete e-KYC verification using Aadhaar, Passport, PAN, Driving Licence, or Voter ID, then activate the account using mobile and email authentication. The portal then prompts users to select the operator profile category linked to their operational role. Individual hobbyist, commercial operator, organisation, importer, and manufacturer profiles each route to different downstream forms, so the profile choice at onboarding determines what the dashboard displays.

The next step opens Form D-2, officially titled the Application for Unique Identification Number. This form replaced the earlier fragmented registration process after the July 2025 migration phase (DGCA Public Notice, 15 July 2025). Operators applying for UIN should ignore Forms D-1, D-3, D-4, and D-5 unless their workflow specifically requires type certification, transfer, RPC issuance, or RPTO authorisation.

After that, the aircraft profile section requires the drone make, serial number, model designation, MAUW category, and type certification reference. Operators with drones not listed in the eGCA manufacturer dropdown select "Other" and fill the manufacturer details manually. The serial number must match the airframe label exactly, because the eGCA portal does not allow serial number edits after submission.

The portal then validates the Type Certificate through the DGCA registry. Aircraft without linked certification records may enter manual verification queues. This remains a common delay point for operators using imported systems or older inventory batches that predate type certification.

The next stage redirects applicants to Bharatkosh for payment processing. Bharatkosh, also called the Non-Tax Receipt Portal (NTRP), is operated by the Office of the Controller General of Accounts under the Ministry of Finance. The official UIN issuance fee is ₹100 under the Drone Rules 2021 fee schedule. Earlier fee structures cited under pre-2021 frameworks no longer apply.

Some operators encounter Bharatkosh session failures during payment processing because the transaction bridge occasionally expires between the DGCA portal and the treasury gateway. In those cases, applicants can reopen the pending application through the Dashboard, navigate to My Applications, locate the pending entry, and retry payment without restarting Form D-2. Operators should not submit a second Form D-2 in parallel, because duplicate applications create reconciliation delays during manual DGCA review.

Once payment clears and verification completes, the DGCA generates the UIN digitally through the dashboard. Operators must download the certificate and physically mark the Unique Identification Number on the airframe according to DGCA identification standards before the aircraft is considered registered for operational purposes.

Fees, timelines, and UIN validity

The drone registration fee in India is ₹100, payable as the UIN fee through Bharatkosh under the Drone Rules 2021 fee schedule. The payment is processed through the Non-Tax Receipt Portal and applies once per aircraft registration.

Drone registration and drone pilot license in India are two separate compliance layers. UIN registers the airframe through Form D-2, while the Remote Pilot Certificate (often searched as drone license India) qualifies the operator through Form D-4. The two forms run on different validity cycles and use different verification chains, and conflating them remains the most common source of misinformation across competitor guides.

Approval timelines vary depending on document completeness and verification complexity. DGCA-linked operational guidance allows up to 15 working days for processing under full compliance review. In practice, the DGCA registration timeline in working days clears at one to seven for domestic registrations with complete documentation, with imported and manually-reviewed cases extending to the official ceiling.

The validity period of the UIN drone India remains the misunderstood area across online drone-registration guides. The UIN itself does not expire after five years. Under Rule 46 of the Drone Rules 2021, the Unique Identification Number remains tied to the airframe unless the aircraft is de-registered, destroyed, exported, or transferred through the approved ownership workflow (Drone Rules 2021, Rule 46). The five-year claim that appears across several online guides reflects the pre-2021 framework and no longer applies.

The Remote Pilot Certificate follows a separate validity cycle. RPCs remain valid for ten years before renewal requirements apply under the Drone Amendment Rules 2022, which replaced the earlier Remote Pilot Licence with the certificate-based system used today (Drone Amendment Rules 2022, 11 February 2022). Operators managing fleet-level compliance should maintain records for ownership transfers, maintenance logs, firmware compliance, and operational approvals because UIN validity alone does not authorise unrestricted operations.

Insurance compliance also runs on its own renewal cycle independent of UIN status, with third-party cover mandated under Rule 44. Operators sourcing cover should review the drone insurance providers in India coverage before relying on standard liability templates.

Imported drones, DGFT, and WPC compliance routing

Imported drones follow an expanded compliance chain because registration alone does not establish legal import eligibility. Operators must first obtain import authorisation through the Directorate General of Foreign Trade before onboarding the aircraft into the eGCA workflow (DGFT Notification, 9 February 2022).

Radio-frequency hardware inside imported unmanned aircraft systems also requires Wireless Planning & Coordination Wing Equipment Type Approval where applicable. This validation ensures the aircraft communications stack complies with Indian spectrum regulations and prevents downstream NPNT firmware rejections.

After completing import and radio approvals, operators register the aircraft through the "Import Drone" workflow inside eGCA. Imported drone registration with DGFT and WPC clearances follows the same Form D-2 path as domestic aircraft, with an additional document panel for import endorsement and ETA references. The Type Certificate drone India linkage validates aircraft design conformity before UIN issuance for non-Nano categories. The DGCA then validates the imported airframe against available certification and ownership records before issuing the UIN.

Imported aircraft operators should also review drone import rules and DGFT and the Remote Pilot Certificate process because operational readiness depends on both registration and pilot compliance. Foreign tourists and short-stay operators follow a separate workflow detailed in foreign tourist drone registration in India.

How UIN connects to NPNT and flight permission on DigitalSky

The UIN functions as the identity layer for India's broader NPNT architecture. Registration alone does not authorise unrestricted flight operations inside controlled airspace.

After receiving the UIN, operators connect the aircraft identity to NPNT-compliant firmware. The aircraft then requests flight permission artefacts from DigitalSky before each eligible operation inside controlled or monitored airspace categories (Ministry of Civil Aviation, 25 August 2021). The permission artefact works as a cryptographically signed operational authorisation linked to the approved mission parameters, including the UIN, the geofenced zone, the altitude ceiling, and the validity window.

The NPNT architecture blocks non-compliant aircraft from starting regulated flights without a valid permission token. Under Rule 19 of the Drone Rules 2021, the airspace classification of the launch location also determines whether the permission artefact is auto-issued, conditionally approved, or refused.

This separation between registration and operational permission explains why operators still interact with DigitalSky after the migration to eGCA. The registration layer moved. The airspace permission layer remains active on DigitalSky infrastructure.

Operators completing DGCA-approved drone training through an authorised Remote Pilot Training Organisation receive their RPC through Form D-4 on the same eGCA portal, completing the operator-side compliance chain. Operators planning beyond green-zone recreational operations should review the Indian drone airspace zone map before mission deployment.

Common drone registration rejection reasons and how to fix them

Form D-2 rejections cluster around six causes. Type Certificate linkage errors remain the leading cause of verification delays, especially for imported aircraft and older domestic inventory batches that predate the current certification regime. The fix is to confirm the Type Certificate number with the manufacturer and re-enter it during the application stage.

MAUW classification mismatches also trigger manual review. Applicants occasionally classify drones under the wrong weight category during onboarding, treating a 1.9 kg drone as Nano when it falls under Micro. The DGCA validates declared weight against certification records during review, and a mismatch routes the application to manual reconciliation. The fix is to verify MAUW against the manufacturer datasheet before submission.

Imported aircraft frequently encounter rejection because applicants omit DGFT authorisation references or WPC documentation. Identity-verification failures during e-KYC also pause processing until manual correction occurs, usually triggered when the Aadhaar or PAN record carries an address or name variant that does not match the application form.

Duplicate serial numbers create another operational issue. This normally happens when second-hand aircraft remain linked to a previous owner profile. Operators must complete transfer or de-registration through Form D-3 before submitting a fresh UIN request, otherwise the application is auto-rejected on the duplicate-airframe check.

Bharatkosh transaction interruptions occasionally leave applications in pending states even after payment completion. In those cases, operators should reopen the application dashboard, locate the pending entry under My Applications, and reconcile the payment reference instead of starting a second application. Filing a duplicate Form D-2 in parallel extends the review timeline because the DGCA must manually close one of the two applications before processing the other.

Multiple drones, ownership transfer, and lost UIN recovery

One eGCA account holds multiple drones under a single registered operator. Fleet operators therefore maintain centralised aircraft records inside a single organisational dashboard, with separate Form D-2 entries for each airframe. The multiple drones single eGCA account workflow suits agricultural cooperatives, survey companies, training organisations, and commercial drone-service operators managing inventory across deployments.

Drone ownership transfer in India operates through Form D-3 on the eGCA portal. The transfer workflow requires the transferor to initiate de-registration or assignment, after which the transferee completes a fresh identity verification and links the aircraft to the new operator profile. The transfer updates the aircraft ownership chain while preserving the original UIN history for regulatory continuity, which matters during enforcement audits and insurance claim investigations.

Lost UIN recovery in India follows a dashboard-based path. Operators who lose UIN access records can re-download the registration certificate through the eGCA dashboard if the aircraft remains linked to the original verified account. Where the original account credentials are also lost, operators should raise a recovery request through the DGCA helpdesk with proof of ownership and identity. The detailed recovery sequence is covered in the lost UIN recovery walkthrough. Where account ownership changed internally inside an organisation, an additional internal verification step may be required before certificate reissuance.

As India expands beyond visual-line-of-sight operations and automated airspace management, the connection between eGCA registration, DigitalSky permissions, and NPNT compliance will become the operational foundation of the country's civil unmanned aviation framework. The Civil Drone (Promotion and Regulation) Bill 2025, currently before Parliament, may consolidate the eGCA and DigitalSky stacks into a single platform; operators should watch for further migration notices through 2026 and updated DGCA public notices on the same.
