How the number is built and checked
A PAN can be checked free on the Income Tax e-filing portal with the Verify Your PAN service, which needs no login. It confirms whether the name on the PAN card and the date of birth match the PAN database and whether the PAN is active or inactive. The user must enter a mobile number and an OTP, which is valid for 15 minutes with three attempts, and one mobile number can verify at most five different PANs a day.
A GSTIN is checked with Search Taxpayer on gst.gov.in, with or without login, by entering the GSTIN or UIN and a captcha. Without login it shows the legal name, trade name, effective date of registration, constitution of business, principal place of business, the cancellation date if the registration was cancelled, and the returns filed in a chosen financial year. After login the page adds the promoters' names, e-way bill history, aggregate turnover and a compliance rating from 0 to 10.
What this does and does not tell you
This page checks arithmetic, not registration. Every GSTIN carries a check digit calculated from the digits before it, which is what catches a typo. Confirming that a business is genuinely registered means asking Central Board of Indirect Taxes and Customs (CBIC), because only they hold the register.
