Defnyddiwch ein teclyn i ddod o hyd i godau deialu llinell tir ar gyfer ardaloedd daearyddol yn y DU, ac fel arall.
Yn gyffredinol, dinasoedd a threfi mawr yw’r ardaloedd, yn hytrach nag ardaloedd llywodraeth leol. Mae’r codau i gyd yn dechrau gyda 01 neu 02 – nid yw rhifau ffôn sy’n dechrau gydag unrhyw beth arall yn gysylltiedig ag ardal.
Nid oes modd i’r teclyn roi:

- gwybodaeth sy’n gysylltiedig â chodau deialu rhyngwladol
- codau deialu ar gyfer codau post.
I gael gwybod costau ffonio'r rhifau hyn a rhifau eraill, ewch i’n canllaw i gostau galwadau.
Mae gennym gyngor hefyd ar beth i'w wneud am alwadau a negeseuon dieisiau neu sgam.
