Bookmakers often use Promo Codes for new customers registering accounts in order to determine which offer it is you may have signed up under.
For example a bookmaker may be running a general free bet of £50.00, and for a weekend may also run a sign up offer specifically to promote a big football match, such as the FA Cup final, or a Champions League final.
In order to differentiate between the two offers, the bookie may well use Promo Codes to identify which offer you signed up to.
The bookie may well run a lot of offers all of the time and therefore would need to use promo codes on their offers. For example Betfair are always running different sign up offers on a weekly basis, and the promo codes are always changing.
I have always found whenever I write about a Betfair offer, that the promo code is already in the relevant box. It’s always worth checking yourself though, and making sure it is the promo code you want.
In general I have found that where a Promo Code is needed, it is generally already in the relevant position on the registration form. For example it may be in a box called ‘Promotional Code’ or ‘Referral Code.’
It’s also worth noting that some bookmakers don’t use Promo Codes. It really depends on the nature of the bookmaker, and how many promotions (if any) that they offer.
Some bookmakers only offer a free bet, and that’s it. So you may well be hunting around for a promo code that doesn’t exist.
