Indian PAN card validator

Completely malformed strings fail with invalid_input instead of inventing a number. Use it free in the browser or call the KIT API at the published price; both paths run the same deterministic rules with no NSDL or UTIITSL network call.

How an Indian PAN is structured and what the fourth character means

When the pattern matches and the fourth character is one of the ten known codes, valid is true and entity_type names the class. When the pattern matches but the fourth letter is not a recognised entity code, valid is false and entity_type is Unknown so callers can highlight the fourth character without treating the whole string as garbage. Completely broken input never returns a synthetic PAN; it raises invalid_input with a message that names the length or character-class problem.

Input contract, response fields, and how validation behaves

Spaces, dots, hyphens, underscores, and slashes are stripped and letters uppercased before the pattern check, so values such as AAAPL one two three four C or AAA-PL-1234-C still parse. After normalisation the engine requires the regular expression five uppercase letters, four digits, one uppercase letter. POST a JSON body with one required string field named pan. Aliases text, input, value, number, s, and id are accepted so thin clients and generic text boxes can reuse the same endpoint without renaming fields. On success the response echoes the trimmed original input, the cleaned pan string, a display formatted field with spaces around the digit block, valid true or false, entity_code as the single fourth character, entity_type as the decoded English label, series as the first three letters, name_initial as the fifth character, sequence as the four digits, check_letter as the tenth character, length ten, scheme pan_india, and entity_codes listing the official fourth-character alphabet for client-side legends. Empty strings, missing pan, pure numbers, wrong lengths, mixed illegal characters, and patterns that are not five-plus-four-plus-one raise invalid_input and are not billed. Because the path is pure parse with no clock, random source, or network, the same input always yields the same JSON on the free browser tool and on the API. Successful calls cost the published base price of $0.002 per item; the in-browser tool remains free for interactive checks. Prefer this specialised endpoint when you need the entity type decoded in the response body, not only a boolean from a generic multi-country tax-id checker.

Where PAN format checks fit KYC, payroll, and data pipelines

Onboarding and KYC forms for Indian customers often ask users to type a PAN before e-sign or bank linkage. Content sites ranking for indian pan card validator or pan format checker benefit from a live tool whose free browser path matches the paid automation path byte-for-byte. Do not treat a passing structural check as proof of identity, allotment, tax filing status, or authorisation to act on someone’s behalf—it only proves the digit-and-letter string is consistent with the public PAN layout and a recognised entity-type code. Validating the ten-character pattern and the entity-type letter at the browser or API edge blocks obvious typos before a record is written and before any downstream tax or payments service is called. Payroll and HR imports receive employee identifiers from spreadsheets where a single swapped digit would reject a whole batch; a deterministic oracle that returns pan, valid, and entity_type lets importers flag rows without calling government portals for every line. Integration tests for OCR pipelines can assert that a cleaned ten-character string either validates or is rejected with a clear invalid_input message when noise remains.
