PAN Number Formatter
TextFormat a raw PAN number into the standard uppercase AAAAA9999A pattern, with an optional spaced display. Strips invalid characters, runs in your browser.
What is a PAN?
A PAN Number Formatter normalises a raw PAN (Permanent Account Number) entry into the standard uppercase, unspaced AAAAA9999A convention — five letters, four digits, one letter. PAN numbers are frequently typed or pasted in inconsistent case, or with stray spaces, especially when copied from forms, emails, or spreadsheets where formatting wasn't enforced.
This formatter cleans that up instantly, converting to uppercase and stripping invalid whitespace, while flagging any input that doesn't match the expected 10-character structure. For checking whether a PAN's structure is genuinely valid (not just formatted), use the PAN Validator.
How to use this PAN calculator
- Paste one or more PAN numbers into the Raw PAN Input field, one per line.
- Select your preferred Output Format — standard compact or spaced for readability.
- Read the formatted, uppercase result for each line in the output panel.
- Check for any "Error" lines, which indicate an entry that isn't 10 characters or doesn't match the AAAAA9999A pattern, and correct the source data.
Formula & Methodology
The formatter strips whitespace and converts the input to uppercase, then checks it against the standard PAN pattern before formatting. Before:abcde1234fAfter (standard):ABCDE1234FAfter (spaced):ABCDE 1234 FThe pattern checked is five letters (A–Z), followed by four digits (0–9), followed by one letter (A–Z) — any input not matching this exact structure after cleanup is flagged as an error rather than guessed at. For background on the underlying term, see our glossary entry on PAN.
Frequently Asked Questions
A PAN (Permanent Account Number) follows the pattern AAAAA9999A — five uppercase letters, followed by four digits, followed by one uppercase letter — for a total of 10 characters with no spaces. This formatter normalises any raw input into that exact uppercase, unspaced convention.
PAN numbers are officially issued and printed entirely in uppercase letters, so a lowercase or mixed-case entry like 'abcde1234f' doesn't match the standard format even though the characters are technically correct. This formatter automatically converts the input to uppercase to match the official convention.
No — this tool only normalises the casing and spacing of a PAN number you provide; it doesn't check whether the number is actually registered with the Income Tax Department. Use the [PAN Validator](/pan-validator-india/) if you want to confirm a number matches the correct structural pattern.
The spaced option inserts visual breaks (ABCDE 1234 F) purely for readability when displaying a PAN on a page or document — it is not an official format, since real PAN cards print the number as one continuous 10-character string. Use the standard compact format for anything that needs to match the official convention exactly.
Yes — enter one PAN per line, and the formatter processes each line independently, showing an error for any line that isn't exactly 10 characters or doesn't match the five-letters/four-digits/one-letter pattern.
The formatter strips any spaces and converts all letters to uppercase before checking the format, so 'abcd e1234 f' and 'ABCDE1234F' both produce the same normalised result. This makes it easy to clean up PAN numbers copied from inconsistent sources.
An error means the cleaned input either isn't exactly 10 characters or doesn't match the AAAAA9999A pattern — five letters, four digits, one letter, in that exact order. Double-check the original number for a transposed character or a digit where a letter should be (or vice versa).
No — formatting happens entirely in your browser using JavaScript. Your PAN number is never transmitted to a server or stored.
This formatter normalises casing and spacing on an already-structurally-plausible PAN number, while the [PAN Validator](/pan-validator-india/) checks whether a number matches the correct format and explains exactly why it doesn't if it fails. Use the formatter to clean up data, and the validator when you specifically need a pass/fail structural check.
