Starting Monday residents outside of Metro Vancouver will have less than two months to get used to punching in 10 digits to make local phone calls.

Users can still use seven-digit dialing without the 250 area code, but they'll have to listen to a gentle reminder to dial the 10 digits. Beginning Sept. 8, only 10-digit calls will be connected throughout British Columbia.

Metro Vancouver phone users were required to punch in the 604 area code in 2001, when the 778 area code was introduced in the region.

The 778 area code will be allocated to users in the rest of the province when 10-digit dialing becomes mandatory.

Shawn Hall, a spokesperson for Telus, said the changes are coming because the phone system is running out of numbers.

"You've got a cellphone, a blackberry, a wireless air card. Both your kids have cellphones, and then your husbands and wives have as many cellphones as you do," Hall said on Friday.
