The Landline Glossary — Line, Number, Area Code, Geographic
Four landline terms, defined once — line, number, area code, geographic — so the landline conversation stops confusing itself. Which this site touches.
Landline conversations go wrong because four different things share one word. This is the glossary — line, number, area code, geographic — defined once, with a note on which terms this site's published products touch and which they deliberately do not.
Term 1: the line
The physical service a carrier provides — copper, fibre or wireless — that carries calls to a premises. The line is infrastructure, sold by carriers, and it is not part of the published range here: no page on this site sells or configures a line.
Term 2: the number
The digits customers dial. A landline's number is attached to its line; an inbound number — 1300, 1800 or a Phoneword — is a published contact point with no line of its own, connected instead to the answering point nominated at sign-up. This site sells the second kind, on plans from $10 per month.
Term 3: the area code
The two-digit regional prefix (02, 03, 07, 08) that starts a geographic landline number. It belongs to the line layer — which is why inbound numbers have none: their prefixes (13, 1300, 1800) are format markers, not regions. No coverage claims are published for inbound prefixes, and this glossary adds none.
Term 4: geographic
The property of being tied to a place. Geographic numbers locate the line; inbound numbers locate the business. A geographic number moves when the line moves; an inbound number stays while the answering arrangement behind it changes. That asymmetry is the entire practical difference between the two families.
Why the glossary pays for itself
Because half of all landline-and-number confusion is a vocabulary collision: someone asks for a "number" meaning a line, or a "line" meaning a contact point, and the seller answers a different question. With the four terms separated, the shopping is clean — lines from carriers, inbound numbers from here — and the join between them (the answering point at sign-up) is the only published place the two worlds touch.

Glossary questions
Is my landline number the same as my line?
No — the line is the physical service, the number is the digits attached to it. The glossary separates them because they are sold, changed and cancelled separately.
Do inbound numbers have area codes?
No — their prefixes (13, 1300, 1800) are format markers, not regions. No geographic meaning or coverage is published for them.
Which term does this site's product use?
Inbound number — a published contact point on a plan, connected to the answering point you nominate. The line and the area code belong to the carrier side.
Can a number stop being geographic?
How numbering properties change is not published material here — that is carrier and industry territory. What is published is the inbound alternative that needs no geography at all.
