No. That's Iraqi Arabic transliterated in the English alphabet. The numbers correspond to Arabic letters that resemble these numbers in shape and that has no phonetic equivalent in the English alphabet. Hence, we resort to using the numbers that look like those letters.
My bad if that's not making sense. You kinda have to know Arabic to understand it.
It's what I use when I chat with my Iraqi friends because:
1-Almost all of us type in English way faster than in Arabic (I personally I'm so bad in typing Arabic I sometimes have to search for the letters)
2-Many of my friends live in the West where there are no laptops with keyboards with Arabic characters.
Well, some live in the Arab world but nevertheless buy laptops that have no Arabic characters because they are "originals" and not Chinese-made
