Under section 25 of the CGST Act, apply separately in each state or UT where registration is required; each registration is treated as a distinct person for GST purposes. A TRN helps you resume an application, but it is not a GSTIN or proof of registration.
Do multiple states share one GSTIN?
No. The phrase “under one GSTIN” is misleading if you need registration in more than one state or Union territory. The CGST Act provides for a registration application in each state or UT where a person is liable to register, generally with one registration in each, subject to exceptions. A customer or project in another state does not, by itself, establish that registration is required there; the answer depends on the business’s facts and applicable law.
Where a person has more than one registration, section 25(4) says the person “shall, in respect of each such registration, be treated as distinct persons for the purposes of this Act.” These are not simply branches using one GSTIN for all compliance purposes. Optional separate registrations for multiple places of business or business verticals within a single state are a related but distinct issue.
What are the TRN and ARN?
- TRN: The Temporary Reference Number is generated after Part A verification. Use it to return to and complete the saved Part B application. It is not the final GSTIN.
- ARN: The Application Reference Number is the acknowledgement issued after successful filing and any required authentication steps. It lets you track the submitted application; it is not itself the granted registration.
The GST Portal manual says a saved application not submitted within 15 days is purged along with information saved against its TRN. The manual’s publication date is not stated, so check the current portal instructions if your application is close to that limit.

How to apply for a state-specific GST registration
- Start Part A for the state or UT. On the GST Portal, choose the applicant type, select the state or UT for this application, and enter the PAN and contact details. Complete the mobile and email OTP checks. The portal displays PAN-linked registrations and generates a TRN after verification.
- Resume Part B using the TRN. Return to the saved application and enter the TRN to continue. Complete the relevant tabs for business details, people, principal and additional places of business, goods and services, state-specific information, authentication and verification. The portal manual notes that the state selected in Part A carries through as the form’s state context.
- Complete the required authentication and submit. The portal describes PAN validation and, where applicable, Aadhaar authentication. Depending on the route applicable to the applicant, authentication may involve OTP or a biometric appointment. Follow the route shown for the application rather than assuming every applicant uses the same method.
- Save the ARN and monitor the application. The ARN acknowledgement follows successful completion of the required authentication and final submission sequence. Use it to track the officer’s review and respond if the portal or officer requests clarification.
- Repeat the process for each other state or UT where liable. A registration granted for one state does not automatically extend nationwide. Start a separate state-specific application for each additional state or UT where the business is liable to register.
What happens after submission?
Under Rule 9 of the CGST Registration Rules, if the application and accompanying documents are found in order, the rule specifies approval within three working days from submission. That is a conditional statutory period, not a guarantee of the total elapsed time for every application.
If the officer needs more information or finds a deficiency, the rules provide for a notice and a response process. The application may also involve verification or an applicable authentication step. Check the status and notices for each ARN separately: one state’s application does not determine the outcome or timing of another state’s application. The official materials do not support ranking states by approval speed.

What to check before applying in another state
- Identify the relevant state or UT and the business’s place-of-business and supply facts.
- Determine whether those facts create a registration liability there; do not infer a requirement solely from having a customer in that state.
- Track each application’s TRN before submission and ARN after submission independently.
- Follow the authentication route and any physical verification requirement shown for that application.
- Respond to any officer clarification request within the stated process and timeframe.
CBIC’s FAQ includes a question about a civil contractor working on projects in multiple states versus registering only at the head-office state. The governing approach is state-specific registration where liability applies, but that general rule does not decide every business’s facts. For a service supplier, the official FAQ gives an example of registration at the location from which services are supplied; it does not resolve every possible supply or project arrangement. Check the current GST Portal and legal text, and obtain qualified tax advice for a fact-specific determination.
