An 06 or 07 number
Two prefixes for one and the same type of line.
06 and 07 both refer to a French mobile. Their only difference is historical: 06 was opened first, then ARCEP added 07 when 06 numbers started running short. Technically, an SMS or a call behaves strictly identically to both.
In summary
- 06 and 07 both correspond to French mobile lines.
- 07 was opened because the reserve of 06 numbers was running out, not to mark a category of subscribers.
- A French number has ten digits, prefix included.
- Neither prefix reveals the holder's operator.
Believing that an 07 would be a lesser-value number, tied to a virtual operator or a low-cost offer, is a baseless shortcut. Blocks of numbers are first allocated to operators by the regulator, then distributed among their subscribers; the same operator holds both 06 and 07 blocks.
This confusion feeds on another shortcut, even more stubborn: the idea that a prefix would reveal the network. That was partly true before number portability. It no longer is: a subscriber can change operator while keeping their number, and commonly does so. As a direct consequence, a number says nothing about its holder.
To send a free SMS, the conclusion is clear: nothing else to know but the ten digits. The form accepts either prefix, and routing to the right network is determined automatically, without you having to specify anything more.
Frequently asked questions
Does an 07 necessarily correspond to a virtual operator?
No. The 07 blocks are distributed to all operators, including the four network operators.
Can you guess the operator by reading the number?
No. Since portability, a number may have changed operator several times without any of its digits moving.
