SWIFT Code Lookup

Overview

A SWIFT code lookup API, SWIFT bank API and BIC lookup that gets bank data from a SWIFT code in one call. Pass an 8 or 11-character SWIFT/BIC code to retrieve the institution's name, branch, city and two-letter country code; an 8-character code also lists the branches under it. Or run a SWIFT code search by institution name to find its codes across branches. The directory holds about 113,000 BIC records from the public ISO 9362 list, covering 232 countries and territories, and each search returns up to 25 matches with a count.

Formula

One function covers the whole catalog: the first argument names the source, the next are its inputs, and the field after them says which single value lands in the cell. Formulas covers the grammar that applies to all of them.

=VERVE("swiftlookup", A2, "count")

A2 holds the swift you are looking up. Drag the formula down and each row resolves on its own.

With literal values

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

=VERVE("swiftlookup", "CHASUS33ARP", "count")

Inputs

Required inputs are positional, in the order below, followed by the field. Everything else is passed as a "name", value pair after that — the same shape as SUMIFS. Premium inputs are accepted on every plan but only take effect on plans that include them.

Input	Type	Where it goes	Description
`swift`Required	string	argument 2 (A2)	The SWIFT code to lookup information about

What lands in your sheet

The field — the argument after the inputs — is what makes the formula resolve to one cell. Its value is a dot-path from the table below, so swapping it is how you pull a different value — one formula per column.

Seeing everything at once

Leave the field out and the formula returns the whole response instead: two columns, field name on the left and value on the right, spilling from the cell you typed in.

=VERVE("swiftlookup", A2)

Good for exploring, not for filling down

The second row's table would land on top of the first's, and every cell after the first reads #REF! (#SPILL! in Excel). Keep one per sheet, or name a field, and leave the cells below and to the right empty.

Response fields

Paths are relative to data. Each one is exactly what the field argument accepts, so swapping it is how you pull a different value into a cell. On a plan without a Premium field the cell reads #PREMIUM(field) rather than a value, so a locked field never looks like a real answer.

Use as the field	Type	Example cell value	Description
`count`	number	`1`	Number of matching SWIFT code records returned, at most 25
`banks`	array[1]		Array of banks matching the SWIFT code lookup
`banks.0.bank`	string	`JPMORGAN CHASE BANK, N.A.`	Full legal name of the bank institution
`banks.0.city`	string	`NEW YORK,NY`	City and state location of the bank branch
`banks.0.branch`	string	`ACCOUNT RECONCILIATION PROCESSING`	Specific branch name and department information
`banks.0.swift_code`	string	`CHASUS33ARP`	The SWIFT/BIC code for the bank branch
`banks.0.country`	string	`United States`	Country name where the bank is located
`banks.0.country_code`	string	`US`	ISO 3166-1 alpha-2 country code
`banks.0.is_eu`	boolean	`false`	Whether the bank's country is an EU member state
`banks.0.is_eea`	boolean	`false`	Whether the bank's country is in the European Economic Area (the EU plus Iceland, Liechtenstein and Norway)
`banks.0.is_sepa`	boolean	`false`	Whether the bank's country is in the Single Euro Payments Area (SEPA), per the European Payments Council
`banks.0.bic_details`Premium	object	`{…}`	The code broken into its ISO 9362 parts, with its 8- and 11-character forms and whether it is the head office or a test code
`banks.0.bic_details.bank_code`Premium	string	`CHAS`	The 4-letter institution code (DEUT for Deutsche Bank)
`banks.0.bic_details.country_code`Premium	string	`US`	The 2-letter country code inside the BIC
`banks.0.bic_details.location_code`Premium	string	`33`	The 2-character location code
`banks.0.bic_details.branch_code`Premium	string	`ARP`	The 3-character branch code; null for an 8-character code
`banks.0.bic_details.bic8`Premium	string	`CHASUS33`	The 8-character form of the code
`banks.0.bic_details.bic11`Premium	string	`CHASUS33ARP`	The 11-character form, with XXX for the head office; some payment forms require this length
`banks.0.bic_details.is_primary_office`Premium	boolean	`false`	True for the head office: an 8-character code or a branch code of XXX
`banks.0.bic_details.is_test_bic`Premium	boolean	`false`	True when the location code ends in 0, which SWIFT reserves for test and training codes that cannot receive live payments

Filling a whole column

Both platforms make one batched call for a column rather than one request per cell, and both cost the same — 10 credits per row looked up. How you write it differs, because the two runtimes batch at different points.

Rows 2–100 in one call

=VERVE("swiftlookup", A2:A100, "count")

In Google Sheets, give the arguments ranges and the answers spill down from the cell you typed in. Custom functions there run synchronously and in isolation, so dragged cells cannot be coalesced — the range form is how a column becomes one call. The field is required here: a per-row two-column table has nowhere to spill. Use a full column per input (A2:A100, not A2) — a single-cell reference is read as row 1 only and the rest of the column comes back blank.

In Excel, type the formula once and fill down — no range form and none needed, because its runtime is asynchronous and the add-in coalesces the calls a fill produces into a single batched request. Do not hand VERVE.CALL a range: Excel flattens it into positional arguments, so A2:A100 arrives as a hundred separate arguments and the cell reads #ERR rather than filling.

Either way, column A holds your swift values and the answers land beside them, one row each, blank rows 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() will not catch it; test with LEFT(cell, 4) = "#ERR" instead. Error handling covers the rest.

Cell reads	What happened
`#ERR Not connected`	No API key saved. Open the side panel and connect your account.
`#ERR Replace <name> with a cell or value`	A preview formula was copied as-is. Swap the placeholder for a cell reference.
`#ERR No "x" in swiftlookup`	An option name this source does not take. The message lists the ones it does.
`#ERR No data point "…"`	The field path is not in the response. Check it against the table above.
`#PREMIUM(field)`	The field exists but your plan does not include it.
`#ERR Out of credits`	The cycle'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 does not leak it and a collaborator without access simply sees the last calculated values.

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

Use cases

Cross-Border Wire Verification: Before initiating an international wire, billing platforms verify the recipient's SWIFT code matches the intended legal entity and destination country.
Vendor Onboarding Form: Auto-fill the bank name, branch city, and country code as soon as a supplier enters their SWIFT code during payment registration.
Branch Code Discovery: Accounting software helps treasury operators locate missing branch SWIFT codes by querying institutional names across international divisions.
Bank Country Screening: Risk engines cross-check the SWIFT country code against sanction lists to flag transfers directed to prohibited financial jurisdictions.
