Writing a cheque so it can't be altered
The written amount exists as a fraud control. Digits can be changed with a pen stroke — a 1 becomes a 4, a 0 gains a companion. Words cannot.
- Write the words to match the figures exactly. If they disagree, banking rules in most countries make the words prevail.
- Start at the far left of the line so nothing can be inserted before your first word.
- Strike through the remaining space with a horizontal line after "pence" or "only".
- Add "only" at the end — common in South Asia and the Middle East, and a sensible habit anywhere.
- Never sign a blank cheque. Obvious, still worth stating.
British and American conventions
The difference is the word "and". British English writes "one hundred and five"; American English writes "one hundred five". American usage reserves "and" for the decimal point, which is why US cheques read "Four thousand two hundred fifty and 75/100".
Both are accepted by banks in either country. Use whichever matches the document's prevailing style, and be consistent within a single document.
The Indian numbering system
Used across India, Pakistan, Bangladesh, Nepal and Sri Lanka, it groups digits in a different rhythm after the first thousand:
| Indian | Digits | International |
|---|---|---|
| 1 thousand | 1,000 | 1 thousand |
| 1 lakh | 1,00,000 | 100 thousand |
| 10 lakh | 10,00,000 | 1 million |
| 1 crore | 1,00,00,000 | 10 million |
| 100 crore | 1,00,00,00,000 | 1 billion |
| 1 lakh crore | 1,00,00,00,00,000 | 1 trillion |
Note the comma placement too: 12,34,567 rather than 1,234,567. Both are shown above the result so you can copy whichever your document needs.
Where written numbers are required
- Cheques and demand drafts — the words are the legally operative amount.
- Contracts — figures are commonly written twice, as "£50,000 (fifty thousand pounds)".
- Invoices — required in several jurisdictions, and standard practice in South Asia and the Gulf.
- Promissory notes and loan agreements.
- Legal filings and deeds, where transcription errors are expensive.
Style notes for formal documents
- Spell out whole numbers under ten in prose; use digits above.
- Never start a sentence with a digit — rewrite, or spell it out.
- Hyphenate compounds from twenty-one to ninety-nine.
- Keep one convention throughout a document. Mixing "one hundred and five" with "two hundred six" looks careless.
Frequently asked questions
How do I write an amount on a cheque?
Write the whole number in words, then the fraction — "Four thousand two hundred and fifty pounds and 75 pence", or in US style "Four thousand two hundred fifty and 75/100 dollars". Draw a line through any remaining space so nothing can be added after you sign.
What is the Indian numbering system?
It groups digits differently: thousand, lakh (100,000) and crore (10,000,000), with commas placed as 12,34,567 rather than 1,234,567. It is standard across India, Pakistan, Bangladesh, Nepal and Sri Lanka, so a figure written as "12 lakh" means 1,200,000.
Should there be an "and" in the number?
British convention includes it — "one hundred and five". American convention omits it — "one hundred five". Neither is wrong; both are offered here. On a cheque, banks accept either, and the numeric box is what actually governs if the two disagree.
Why do contracts write numbers twice?
Because words are far harder to alter than digits, and a discrepancy is easier to spot. If the two conflict, most legal systems and banking rules treat the written words as authoritative — which is exactly why the words are there.
How large a number does this handle?
Up to quadrillions in international format and up to crores of crores in Indian format. Beyond about 15 digits, JavaScript numbers lose precision, so very large values are rejected rather than silently rounded.
