A Bolivian phone number checker reads a number's format first and then checks it against Bolivia's numbering plan.
This is the path one check takes. A number can be written correctly and still not be assigned to anyone, so the format check alone is not the answer.

Three common mistakes make a Bolivian number fail the check, and each one is quick to fix.
Repeating +591 adds digits.
Write +591 71234567 once, with the country code at the front.
Typing too few or too many digits makes a number invalid.
A mobile number has 8 digits after +591. With 7 or 9 it cannot be a valid mobile, so look for a missing or doubled digit.
Leaving the wrong country selected changes how the number is read.
The checker reads a number by the rules of the country selected above, so keep Bolivia selected for a +591 number. Paste a number with its + and country code and the country is read from the number itself.
These are the questions people ask most about checking Bolivian phone numbers.

Does the person know I checked their number?
No. The check reads records only. No call or text goes to the number, so its owner is never told.
