The problem that you probably did not guess

As it is known, in Russia for receiving a SIM card it is necessary to present a passport and be of legal age. The address is written, name, you must sign. It is also known that Russia is a big country. And in every more or more large city, a large number of postal codes are used, although the official one (for an example, you can go to Wikipedia). If you look at the passport, then on the stamp with registration is missing this very zip code. And now the question: where does the correspondence go? That's right, in the branch with the specified index.

But when registering a SIM card, they usually DO NOT ask for the index, since data is filled with a passport. It came to me by chance, I went to my personal account on the site of the operator to which I recently connected. Fortunately, you can change the data, otherwise the wrong index would remain so.

Why am I doing this at all ... Suppose you got into the negative and forgot about it. You are happy to pay, but there is no one to remind you. And then it is not known what this might be fraught with. I mean non-repayment of debt, failure to appear in court, etc.
