Validate Phone Numbers in SheetsValidate Phone Numbers in Sheets

OnlineCredit Usage:1 per cell

Formula

Check numbers by the row. =VERVE("phonenumbervalidator", A2, "us") flags whether each phone number is valid — Google Sheets or Excel.

In a cell
=VERVE("phonenumbervalidator", A2, B2)
In a cell
=VERVE.CALL("phonenumbervalidator", A2, B2)

A2 holds number, B2 holds country. Arguments go in that order — the same order as the table below.

With literal values

Nothing has to come from a cell — typed values work the same way.

Sheets
=VERVE("phonenumbervalidator", "816-555-1017", "us")

Inputs

Required inputs are positional, in the order below. Everything else is passed as a "name", value pair after them — the same shape as SUMIFS.

InputTypeWhere it goesDescription
numberRequiredstringargument 2The phone number to validate (e.g. 816-555-1017)
countryRequiredstringargument 3The country code of the phone number (e.g., us, uk) (e.g. us)

What lands in your sheet

With no "field" pair the formula spills the whole response as two columns — field name on the left, value on the right — starting at the cell you typed in. Make sure the cells below and to the right are empty.

Pulling one value

Add a "field" pair to get a single cell back instead of a table. The field name is the dot-path from the table below.

Returns country
=VERVE("phonenumbervalidator", A2, B2, "field", "country")
Returns country
=VERVE.CALL("phonenumbervalidator", A2, B2, "field", "country")

Available fields

Fields marked Premium need a paid plan. On the free plan those cells read #PREMIUM(field) rather than a value, so a locked field never looks like a real answer.

Filling a whole column

Hand the first argument a range instead of a cell and the add-in makes one batched call for the lot, then spills the answers down. That is faster than dragging the formula and costs the same credits — one per row looked up.

Rows 2–100 in one call
=VERVE("phonenumbervalidator", A2:A100, B2, "field", "country")
Rows 2–100 in one call
=VERVE.CALL("phonenumbervalidator", A2:A100, B2, "field", "country")

A2:A100 is the column of number values. The result spills down alongside it, one row per input, blanks skipped.

When a cell doesn't fill

A failed lookup returns readable text starting with #ERR rather than a spreadsheet error, because Excel cannot show a custom message on a real error — you would get a bare #VALUE! with no reason. The trade-off is that IFERROR() won't catch it; test with LEFT(cell, 4) = "#ERR" instead.

Cell readsWhat happened
#ERR Not connectedNo API key saved. Open the side panel and connect your account.
#ERR Replace <name> with a cell or valueThe preview formula was copied as-is. Swap the placeholder for a cell reference.
#ERR No "x" in phonenumbervalidatorAn option name that this source doesn't take. The message lists the ones it does.
#ERR No data point "…"The "field" path isn't in the response. Check the dot-path against the table above.
#PREMIUM(field)The field exists but your plan doesn't include it.
#ERR Out of creditsThe month's credits are spent. Usage resets on your billing date.

Before the formula works

The add-in reads the API key you saved once in the side panel — the key never goes in the formula, so a shared sheet doesn't leak it and a collaborator without access simply sees the last calculated values.

  1. Install the add-in for Google Sheets or Excel.
  2. Open the side panel and sign in, or paste a key from your dashboard.
  3. Type the formula above into any cell.

Frequently asked questions

Does Validate Phone Numbers in Sheets work in both Google Sheets and Excel?

Yes — the same source, the same arguments. Sheets calls it =VERVE("phonenumbervalidator", …) and Excel calls it =VERVE.CALL("phonenumbervalidator", …); that function name is the only difference.

Do the cells recalculate on their own?

They recalculate when the sheet does — on edit, on open, or on a manual recalc. Each recalculation is a fresh call and spends credits, so for a large static column it's worth copying the results and pasting them as values.

How many credits does a filled column cost?

1 credit per row looked up, whether you drag the formula or pass a range. The range form is one HTTP call instead of many, but the credit count is the same.

Can I share the sheet without sharing my key?

Yes. The key is stored against your account, not in the file. Collaborators see the values already in the cells; formulas only recalculate for someone who has connected their own account.

Why is a cell showing #ERR instead of an error?

So you can read the reason. Excel can't display a custom message on a real spreadsheet error, so the add-in returns the explanation as text on both platforms instead.
