How do I search for a CPHH or postcode? Sut ydw i'n chwilio am Rhif y Daliad neu god post?

Centring the map on a specific area in England or Wales can be achieved via the search facility (the magnifying glass in the top right hand corner). Clicking the dropdown this gives you the choice of searching by CPHH or by postcode. Gellir mynd at ardal benodol yng Nghymru neu Loegr drwy'r cyfleuster chwilio (y chwyddwydr ar frig yr ochr dde). Mae clicio yma yn rhoi'r dewis i chi chwilio fesul CPHH neu god post.

Enter the search term in the input box. If a CPHH is entered it needs to conform to the format --/---/----/-- (including the slashes). As you type a set of results will appear below. Rhowch y term chwilio yn y blwch mewnbwn. Os nodir CPHH mae angen iddo gydymffurfio â'r fformat --/---/----/-- (gan gynnwys y slaesau). Wrth i chi deipio, bydd canlyniadau'n ymddangos islaw.

Select a result from the list and click the search button to centre the map. Dewiswch ganlyniad o'r rhestr a chliciwch ar y botwm chwilio i ganoli'r map.

Please note that the search simply centres the map on either the CPHH or postcode. It is not a search for a breakdown. Noder bod y chwiliad yn canoli'r map yn syml naill ai ar y CPHH neu'r cod post. Nid yw'n chwilio am achos.
