Checking Bulk GST Numbers (GSTIN) – Fast, Clean and Error Free

When I joined my new company, one of my biggest challenges was GSTIN validation.
I had more than 500–600 GST numbers to verify — not just numbers, but also their legal name,
active or deregistered status, and other compliance details. After spending hours searching for a solution,
I finally found this website which solved my entire problem in just 10 minutes!
This is not a sponsored post — I’m simply sharing my personal experience so that accountants, MSMEs,
and compliance teams can save time and avoid manual errors.
1) What is Bulk GSTIN Validation?
Bulk GSTIN validation means checking many GST numbers together in a single attempt. Instead of opening the GST portal and searching each GSTIN one by one, you can simply prepare a list of GST numbers in Excel, paste them into a validator tool, and get all the results in one go. This saves a huge amount of time for accountants, MSMEs, and compliance teams, especially when the list runs into hundreds of vendors or customers. You instantly know which GST numbers are active, cancelled, or have data mismatches, so you can take action before filing returns or making payments.
2) Before You Start (Excel Clean-up)
A clean list means faster validation and fewer “invalid GSTIN” errors. Spend a few minutes preparing your Excel sheet before pasting it into any validator:
- ✅ One GSTIN per row: Keep your list in a single column with no blank rows in between.
- ✅ Remove extra spaces: Use
=TRIM(A1)
in Excel to eliminate invisible spaces. - ✅ Convert to uppercase: Apply
=UPPER(A1)
so all characters are capitalized. - ✅ Check length: Every GSTIN must have exactly 15 characters.
- ✅ Clear hidden junk: Watch for copied bullets, special symbols, or hidden line breaks.
=TRIM(UPPER(A1))
This single formula cleans extra spaces and converts to uppercase in one step. Drag down to apply to your whole list, then copy → Paste Special → Values.

7) TallyPrime vs GSTZen – Which Should You Use?
Bulk GSTIN validation is no longer a luxury — it’s a compliance necessity. Today, both TallyPrime and third-party tools like GSTZen allow you to validate dozens or even hundreds of GST numbers in one go. But which option is right for you? The answer depends on how you manage your books, how often you need to validate, and what level of detail you expect from the results.
If you already use Tally daily to maintain ledgers, running validation from within the software can save time — because it directly updates your books and shows mismatches side-by-side. But if you only have a raw Excel list of vendors and don’t want to touch your accounting data, GSTZen can do the job faster with no setup. The table below compares them feature by feature so you can decide confidently.
🔑 Feature | TallyPrime | GSTZen Validator |
---|---|---|
🔧 Setup Required | Needs GST enabled under F11 (Features), plus e-Invoice or e-Way Bill feature activated. You must enter valid NIC portal credentials so Tally can fetch GSTIN data online. | Zero setup. Open the free validator page, paste GSTINs and hit Validate. Perfect for a one-time project or vendor onboarding check. |
📊 Bulk Capacity | Can validate all selected party ledgers in one go. Large datasets work, but processing time depends on internet speed and portal response. | Handles about 500 GSTINs per batch. For very large lists, simply split and validate in 2–3 rounds. |
🗂 Data Shown | Displays Legal Name, Trade Name, GST Status (Active/Cancelled), Address and HSN/SAC validation (if available). | Shows Legal Name, Trade Name, State, Taxpayer Type. Paid plan adds full address and current registration status. |
🧾 Audit Trail | Gives a clear “As per Books” vs “As per Portal” comparison so you can correct masters instantly and stay audit-ready. | Allows you to download Excel/CSV with time stamp — useful for maintaining an offline compliance record. |
💰 Cost | No extra fee if you already own a TallyPrime license. | Free for basic checks. Paid version is subscription-based for larger volumes and detailed data. |
🎯 Best For | Companies maintaining all books in Tally and wanting direct integration with ledgers. | Accountants, MSMEs, or consultants who just have a vendor list and want quick validation without touching books. |
Bottom line: If your workflow is fully inside Tally, its bulk validation is convenient and keeps data synced. But for speed, one-off checks, or vendor onboarding, GSTZen wins — no logins, no configuration, just paste and validate. Many professionals even use both: GSTZen for a quick pre-check and Tally for final book-level corrections.

8) Frequently Asked Questions
Q1. How many GSTINs can I validate at once?
You can check up to 500 GSTINs at a time in most free tools (like GSTZen). If you have more, split them into batches for faster processing and fewer timeouts.
Q2. The tool shows “Invalid GSTIN” but I am sure it’s correct. What should I do?
First, clean the data — remove hidden spaces, special characters, or formatting issues. Use Excel’s =TRIM()
and =UPPER()
before pasting. If it still fails, verify the GSTIN on the official GST Portal Search Taxpayer page or re-check the original GST certificate.
Q3. Can I copy-paste directly from Excel?
Yes. Keep one GSTIN per row, use =TRIM()
to remove spaces, convert to uppercase with =UPPER()
, and then copy-paste directly into the validator.
Q4. Will I get address and registration status in the free version?
No. Free versions usually show Legal Name, Trade Name, State, and Taxpayer Type only. For current registration status and full address, use the paid version.
Q5. Is the validation result proof for GST audit?
Yes, but always save or export the results with date and time. This acts as an audit trail in case of future disputes or ITC mismatches.
