How to convert 7-digit phone number to 8-digit phone number?

I know it has been a long time since most Taipei phone numbers have
been converted to 8 digits.

However, I still have a bunch of friend in Taipei.(obiviously haven’t called
them in a while) How do I know what their old 7-digit number is in the
new 8-digit format? Do I simply add “2” or “8” in front?

Example: (02)762-XXXX, (02)717-XXXX, (02)658-XXXX

Thanks for any info!

Yes, add a 2 to the front if the number (after the 02 area code).

Sometimes add 8, if they have ISDN line. That’s what I have seen out here anyway.

[quote=“X3M”]Sometimes add 8, if they have ISDN line. That’s what I have seen out here anyway.[/quote]The 8 would already be added. The only way to get 56Kbps through a modem is if one end is digital. Converting the signal twice between analog and digital degrades it too much and makes 33Kbps the maximim possible. Those numbers begin with an 8. Oh yes.

Anyway, if it’s 7 digits, you add a 2, and only a 2.

Old number: (02)762-XXXX, (02)717-XXXX, (02)658-XXXX
New Number: (02)2762-XXXX, (02)2717-XXXX, (02)2658-XXXX

Thanks you guys… the number all work fine after I added the 2 in front.

Fortunately, all of my friends still thave the same phone numbers… but
it was really hard finding excuses about not calling them in years.
(some didn’t even know I left the country years ago…) me bad…
