Change in header contact per location US & UK

coding query regarding geocentric display

[simka]

In the early development stages of planning a new website (to be hosted in US) - considering a .com version of the site to display a US contact tel in the header as the main tel info (with smaller UK number underneath). If the site is found in UK the UK contact tel number will appear as the main number and the US will be the smaller. Unsure whether this can be done but would appreciate input.

Thanks in advance.

will you be showing these on the same url?
are there any other regional differences?
how do you intend to identify US and UK visitors?
what do you have planned for non-US/non-UK visitors?

It should be simple enough to do; you need an IP database. As the UK has a much smaller number of IP blocks, just get the UK list. Run a check on page load, and set a cookie to indicate what you just learned (check on privacy requirements here).

Choice of UK phone number will be critical to your success in the UK.

Numbers beginning 084x, 087x, 070 and 09xx are premium rate and cost a lot to call, especially from a mobile. Savvy customers avoid calling these types of numbers. Some of these numbers cannot be called from outside the UK.

Numbers beginning 080x are free to call from a landline, but are expensive to call from a mobile. There are proposals that one day these numbers will also be free to call from all mobiles.

Only numbers beginning 01xx[x][x], 02x and 03xx are inclusive in free minutes from both landlines and mobiles. They are charged at geographic rate when there are no free minutes.

g1smd: thanks for the input on the numbers - taken note

No problem at all. Inform the user that the cookie is there to distinguish US and UK users to ensure they get the right content.

that's good because a US IP address is going to be crawling your site with bing/googlebot so the US version of the content is what will be indexed by the search engines for those urls.
