The short answer: in Kenya, write call centre. It is the British spelling, Kenya follows British convention in official and business writing, and it is what the people reading your material will expect to see.
The longer answer is more interesting, because almost nobody is consistent about it — including, probably, you.
Where the two spellings come from
English has a batch of words that end in -re in British usage and -er in American: centre and center, metre and meter, theatre and theater. There is no difference in meaning and never has been. Both come from the French centre; American spelling was deliberately regularised in the nineteenth century to match how the word sounds, and British spelling kept the French ending.
So a call center and a call centre are the same thing: a team whose job is to handle telephone calls, and the system that gets those calls to them. Nobody in the industry hears a distinction. If a vendor tells you one term means something more serious than the other, they are selling you something.
Which one Kenya actually uses
Kenyan English follows British spelling. Government documents, the Communications Authority, Kenyan newspapers, university writing and the Companies Registry all use centre. A business registered here with “Call Center” in its name looks slightly like it was typed in a hurry.
And yet center turns up constantly in Kenyan material — on job adverts, in LinkedIn titles, in company slide decks. There is a straightforward reason. The vocabulary of this industry arrived through American software and American outsourcing. If you learned the trade on a US platform, read US blogs about workforce management, and worked for a BPO serving American clients, you learned to spell it center, because that is what was written on every screen you looked at.
Neither habit is wrong. One is the local convention; the other is the industry’s working language.
Why this matters more than it should
It matters because of search. Somebody looking for a system to answer their phones will type one spelling or the other, and a search engine does not treat them as fully interchangeable. A page that only ever says centre is competing for a smaller pool of searches than it could be, and the same is true in reverse.
The split in Kenya is not even. Most local searches use centre, which is what you would expect. But a meaningful share — particularly from people shopping for software rather than for a job, and particularly anything typed on a phone with an American keyboard dictionary helpfully correcting them — uses center. If you sell to that group and your website never spells it their way, you are invisible to a slice of your own market.
What about the other words?
The same split runs through the rest of the vocabulary, and it is worth knowing which is which before you print a job advert:
- Centre / center — as above. Centre in Kenya.
- Organisation / organization — -sation is the British form and the Kenyan default, though -zation is accepted and the Oxford dictionaries prefer it. Nobody will blink at either.
- Analyse / analyze, recognise / recognize — British -se here.
- Dialling / dialing, labelled / labeled — British English doubles the consonant. “Predictive dialling”, not “dialing”.
- Enquiry / inquiry — not actually a spelling difference. British usage traditionally splits them: an enquiry is a question, an inquiry is a formal investigation. “Customer enquiries” is the one you want on your website.
None of this is worth an argument. It is worth ten minutes of consistency, once, so your material does not look like it was assembled by four different people — which is how most company websites in fact read.
What to do with your own site
Three things, in order of how much they are worth:
- Pick one spelling for your prose and hold it. In Kenya that is centre. Fix the pages that disagree, including the ones nobody has looked at since the site launched.
- Give the other spelling a real home. One page or one article that uses it naturally and explains that the two are the same word. That is enough to associate your business with both, and it does not require you to write badly anywhere.
- Check your business name and your Google listing. These are the hardest to change later and the most often wrong. Whatever is on the certificate of incorporation is what should be on the website.
And if you are the person who has been typing center for eight years because that is what the software said: you are not wrong about the industry, only about the country. Carry on in your internal documents. Spell it centre where customers can see.
So which do we use?
Our domain says callcentre.co.ke, because we are Kenyan and that is the correct spelling here. We also answer to call center, and there is a page written in that spelling for the people who search that way. Same software, same Kenyan numbers, same price in shillings. The spelling was never the thing that mattered — whether anyone answers the phone is.
