What is the difference between social insurance registration number and unit medical insurance number?

The unit has no medical insurance number and social insurance registration number.

There is only one unified payment unit code, which is 6 digits.

Only individuals have medical insurance numbers and social insurance registration numbers.

And they are the same number, which used to be 6 digits, but now it is 7 digits.

The above is only from Jiangsu, and other provinces and cities don't know.
