UK private number plates work because the 26 letters and 10 digits of the registration format can, with imagination, spell names, words and phrases. Some substitutions feel natural (3 for E); others feel forced (8 for B). This guide explains the full substitution table, shows you the most recognisable UK examples, and gives you a live converter to try your own name.
The substitution table
Here's the complete UK plate substitution set we use when sourcing for clients. Strong substitutions read almost invisibly on the road; weaker ones need context or explanation.
The bold letters above are the strongest substitutions - these are the ones you'll see most commonly on high-value plates because they read cleanly at a glance.
A good plate needs at most one substitution to spell the intended word. Two substitutions is a compromise. Three is a gimmick. The price drops accordingly.

These are real UK plates people own because they read as a word or name at first glance.
Is it legal to display a substituted plate?
The plate itself is legal - DVLA issued it, after all. What's not legal is how the plate is displayed. You cannot:
- Rearrange character spacing to make it read as a word (e.g. M4 RKS displayed as MARKS with the space removed or moved)
- Use fancy fonts, italics or curves instead of Charles Wright
- Add stickers, tinting, or fixings that alter how the characters read
- Use a 4D / gel / carbon-fibre plate that isn't BS AU 145e certified
Non-standard spacing is the most common violation. A £1,000 fine, an automatic MOT failure, and potentially a voided insurance claim. Always use a Registered Number Plate Supplier and tell them to follow DVLA spacing to the millimetre.
What makes a "clean" read vs a forced one?
A clean read: the substitutions look so natural that most observers don't notice any numbers at all. R053 reads ROSE because 0 and O are visually identical, and 5 for S is instant. M4 RKS reads MARKS because 4 for A requires only the mildest mental shift.
A forced read: requires context to make sense. BO02 SHR reading "BOSS HR" is a stretch; D34 DLY for "DEADLY" needs two substitutions (3 for E, no substitution needed for the rest, but the D in position 1 doesn't obviously start the word in plate format). Buyers who understand plates pay materially less for forced reads.
FAQ
Can I swap 6 for G on my plate?
6 for G is a weak substitution because the rounded shape differs visually. You'll see it on cheaper plates (G16 for "Gig"), but it doesn't command premium pricing. Use it if the letter G is essential and no cleaner option exists.
Why is 5 for S so premium?
5 and S look almost identical in the Charles Wright font used on UK plates. At 30 feet, a driver cannot tell the difference. That "perfect illusion" is why plates like B055 (BOSS), L055 (LOSS), BR05 (BROS) and R055 (ROSS) all command 2-3x the price of plates with weaker substitutions.
Is there a 7 for L substitution?
Rarely, and only in lowercase handwriting contexts (7 looks like a tall L if you squint). On a formal UK plate it reads as T almost universally. We don't recommend marketing a plate as a 7-for-L read.
