=VERVE("ibanvalidator", "GB29NWBK60161331926819", "field", "isValid")

IBAN Validator checks an IBAN's mod-97 checksum, its length and format for the country, and national check digits where the country defines them. It returns whether the IBAN is valid, the country and the reasons it fails. Paid plans add the bank code, branch code and account number, the correct check digits and the SEPA flag.

It's one of 250+ live sources you reach with a single =VERVE() function — served from APIVerve's production data engine, billed at 2 credits per resolved cell, and refreshed on whatever cadence you set. No API keys to wrangle, no scripts, no exports.

A real example — the input you type, and the values you can pull from it. Click any cell to see the formula behind it.

Validate a list before you use it

Run =VERVE("ibanvalidator", "GB29NWBK60161331926819", "field", "isValid") down a column of inputs and let each row tell you whether it's real and safe — catch the bad ones before they hit your workflow.

Score a lead or signup sheet

Add a validity column beside your contacts so you can filter, sort, or conditionally format the rows worth keeping.

Guardrail with IF

Wrap =VERVE("ibanvalidator", "GB29NWBK60161331926819", "field", "isValid") in an IF and flag anything that fails, turning a raw import into a checked, trustworthy sheet.

The same function works in both apps — install once, sign in with your key, and type it into any cell.

Google SheetsAdd-on

Install from the Workspace Marketplace, then drop the formula into a cell. Autocomplete suggests the source and its fields.

=VERVE("ibanvalidator", "GB29NWBK60161331926819", "field", "isValid")
Microsoft ExcelAdd-in

Same source, same arguments, same key — in Excel on desktop, the web, or mobile. Excel namespaces it as VERVE.CALL. Drag to fill a whole column.

=VERVE.CALL("ibanvalidator", "GB29NWBK60161331926819", "field", "isValid")

Add a field name as the last argument to land just that value in the cell.

Premium marks data included on paid plans. On the Free plan a marked field is withheld and a marked input is ignored — either way the cell reads #PREMIUM(name) instead of a value, so a gated answer can never be mistaken for a real one. Everything unmarked works on every plan. Compare plans

IBAN Validator, answered

Everything you need to wire it into a sheet.

How do I pull IBAN Validator into Google Sheets?
Install the VerveSheets add-on, sign in once with your key, and type =VERVE("ibanvalidator", "GB29NWBK60161331926819", "field", "isValid") into any cell. The "field" argument names the value you want back, so the cell resolves to a single number or string you can chart, sort, or feed into another formula.
What data can I pull from IBAN Validator?
IBAN Validator returns isValid, formatted, countryCode, countryName and checkDigits, plus 3 more — name any one of them as the "field" argument and that value lands in the cell. Leave the field out and the whole record spills into a two-column table instead.
Which IBAN Validator fields need a paid plan?
bban, bankCode, branchCode and accountNumber are included from the Starter plan up. On the Free plan the cell returns #PREMIUM(field) rather than a wrong or empty value, so it's always obvious which one to upgrade for. Every other field works on Free.
Can I fill a whole column of IBAN Validator at once?
Yes. Put your iban values down a column and point the formula at the range — A2:A50 instead of A2 — and one call returns a value for every row. Dragging the formula down works too, but the range form is a single billed call per column rather than one per cell.
How many credits does each IBAN Validator cell cost?
Each resolved cell costs 2 credits. A cell only re-bills when it actually refreshes, so a sheet you aren't touching doesn't keep charging.
Does IBAN Validator work in Excel as well as Google Sheets?
Yes — same arguments, same key, same fields. Excel namespaces custom functions, so the call is =VERVE.CALL() there and =VERVE() in Google Sheets; nothing else about it changes.

Put IBAN Validator in your next spreadsheet. Add the extension, paste the formula, and the cell keeps itself current.
