Who holds these numbers

CoopTel de telecommunication holds every prefix here. Code by code: CoopTel de telecommunication is the only holder in 450.

Wireless and wireline

None of Lawrenceville’s holders carries a mobility brand in its registered name: all 1 prefixes belong to wireline or wholesale carriers, among them CoopTel de telecommunication. A call showing a Lawrenceville number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

The register dates none of Lawrenceville’s assignments: all 1 prefixes predate CNAC’s record-keeping, the signature of an old, settled network where nothing has been added in decades.

CoopTel de telecommunication is the only carrier ever recorded for Lawrenceville: no competitor has obtained a prefix here. A single-carrier rate centre is typical of small communities where only the incumbent ever built a network.

Lawrenceville has just 1 prefix (10,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

The local market is an allocation monopoly: CoopTel de telecommunication holds every prefix, and no competitor has ever requested a code for Lawrenceville.

Dialling a Lawrenceville number

A single area code, 450, covers Lawrenceville, and it is not overlaid with any other code on this territory: one of the few parts of Canada where seven-digit local dialling may still work. From abroad, dial +1 450 and the seven-digit number.

The numbering neighbourhood

Lawrenceville shares area code 450 with at least 20 other rate centres, including Granby, St-Jerome, Joliette, St-Lambert, Longueuil, St-Hyacinthe, Pont-Viau and Sorel. The largest of them, Granby, holds 31 prefixes in 450; the smallest on the list, Terrebonne, has just 11.

What a Lawrenceville number tells you

A number attached to Lawrenceville tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often CoopTel de telecommunication. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 1 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and a Quebec area code is easy to borrow to look local.

Reading a register entry for Lawrenceville: code 450-535 is recorded for CoopTel de telecommunication, so every 450-535-XXXX number (10,000 possible) descends from that assignment. “Lawrenceville, Quebec” there names a rate centre, not a municipality.
