1800 Number Format
How an 1800 number is formatted — the 1800 prefix, the six digits after it, and the word form that maps onto them — with a worked example from the published mapping.
The format of an 1800 number is fixed and simple: the four-digit prefix 1800, followed by a six-digit span that identifies the specific number. Two formats share that structure — the numeric form (1800 123 456-style digit groups) and the word form, where some or all of the span is written as letters that map onto digits under the published keypad mapping. This page sets out both, and one worked example.
The numeric form
Six digits after the prefix, arranged through the team — nothing published prescribes how businesses space the digits when writing them, only that the number is 1800 plus six digits and carries no area code.
The word form
Under the published keypad mapping — 2 = ABC, 3 = DEF, 4 = GHI, 5 = JKL, 6 = MNO, 7 = PQRS, 8 = TUV, 9 = WXYZ, with 0 and 1 carrying no letters — a word of up to six letters occupies the span. Worked example: FLOWER as six letters — F = 3, L = 5, O = 6, W = 9, E = 3, R = 7 — maps to 356937 on an 1800 or 1300 base. Word pricing starts from $40 per month, with availability and desirability affecting the specific word.
What the format does not include
Stated plainly: no area code — the number is state-neutral; no country code is published as part of the format here; and a search on Find a Number by word or last six digits shows candidates in the current listing, but availability settles at the team's confirmation, never at search. Plan rows run $10, $15, $39, $79 and $99 per month on the pricing page.

Format questions
How many digits are in an 1800 number?
The prefix (1800) plus a six-digit span — ten digits in total, with no area code.
Can part of the span be letters and part digits?
The published mapping describes words of up to six letters occupying the span. Mixed letter-and-digit formats are not documented on this page — confirm specifics with the team.
Why do 0 and 1 never appear in a word?
They carry no letters on the telephone keypad, so no word can map across a position holding 0 or 1.
Is there a standard way to write the number?
Nothing published prescribes spacing. The substantive facts are the prefix, the six-digit span, and the word mapping where applicable.
