Find phone number with GSTIN checks are not only for buyers and suppliers. Job seekers increasingly receive offer letters, appointment letters and “onboarding kits” that print a GSTIN to look official. Some are genuine. Many fake job offers use real-looking letterheads with a GSTIN copied from a real business or simply made up, then ask the candidate for a registration fee, a training deposit or bank details. A few minutes spent checking the GSTIN and calling the employer on a number you found yourself can save money and protect your identity.

This guide shows how to check an employer’s GSTIN, how to find an independent phone number for the employer, and which signs mean you should stop.

Quick answer

  • A GSTIN on an offer letter does not prove the job is real.
  • Check that the GSTIN’s legal name and address match the employer named in the letter.
  • Find the employer’s phone yourself instead of using the number in the offer.
  • Genuine employers do not charge candidates fees for jobs.
  • Report fake offers to the national cybercrime reporting channels.

Why Fake Offers Quote a GSTIN

A GSTIN looks technical and official, and most people do not know they can check it. Fraudsters print one to borrow credibility, sometimes using the GSTIN of a well-known company so that a quick search seems to confirm the offer. The check is not whether the GSTIN exists, but whether it belongs to the employer in the letter and whether that employer is really offering you the job.

Signs to check alongside the GSTIN when you find phone number with GSTIN for an employer.

Step One: Verify the GSTIN

Enter the GSTIN in the public taxpayer search. Note the legal name, trade name, status, constitution and address. Compare them with the letter. The company name should match the legal or trade name; the city should match where the office is said to be; and the status should be active. A cancelled registration, a mismatch in name, or an individual’s proprietorship pretending to be a large company are all warning signs.

Key pointA real GSTIN belonging to a different business is the most common trick. Always match the name, not just confirm that the number exists.

Step Two: Find an Independent Number

Do not call the number printed in the offer or the one that contacted you; if the offer is fake, that line belongs to the fraudster. Search the employer’s legal name and city to find its official website, and use the contact or careers page. For companies, the corporate registry shows the registered office and a filed email. Map listings for the office address may show a reception landline.

Step Three: Ask the Employer Directly

Call the number you found yourself and ask for human resources or the recruitment team. Give the name of the person who contacted you, the role and the date of the letter, and ask whether the offer is genuine. Large employers often publish warnings about fake offers on their careers pages and keep an email address for reporting them.

Other Signs of a Fake Offer

Offers made without any interview, unusually high pay for little experience, email addresses on general webmail domains rather than the company’s domain, pressure to accept within hours, and requests for bank login details, card numbers or one-time passwords are all common in fake recruitment. So are letters with spelling mistakes in the company’s own name.

What Not to Share

Until the offer is confirmed, do not send money, bank passwords, card details, codes received on your phone, or scans of identity documents beyond what a genuine employer would need after you join. Legitimate employers collect documents through their official onboarding systems after a real interview.

Reporting a Fake Offer

If the offer is fake, report it through the national cybercrime reporting portal or helpline, and inform the real company whose name or GSTIN was misused so it can warn others. If you have already paid, report quickly and contact your bank at once; speed improves the chance of stopping the transfer.

Helping Others

Share what you found with fellow candidates, campus placement cells or online groups where the offer circulated. A quick note that the GSTIN belongs to a different business, and that the real employer denied the offer, can stop others from paying.
