In any measurement, the accurately known digits and the first doubtful digits are called significant figures.
Significant figures
Suppose you have a variable whose exact value is not known. Repeated estimations give values which match up to a certain degree but beyond that they are different. You could take some sort of [weighted] average of the leading digits of these different parts and your estimate for the variable wold be the matched part with the estimated digit appended.For example, if you Google "mass of proton" the WIkipedia site give it as ‎1.672621898(21)×10−27 kg. The (21) - in parentheses - indicates that those two digits are estimated.
Accurately known digits along with first doubtful digit are called significant figures.
As of October 2015, the largest known prime number is 2^57,885,161 − 1, a number with 17,425,170 digits.
Significant digits in measurement refer to the digits in a number that carry meaning or contribute to the precision of the measurement. They indicate the level of accuracy or certainty in a measurement, with each significant digit representing a reliable and known value.

There are many codes that use 5 digits systems. One of the best known ones is the US postal service ZIP CODES. In health care, there is a 5 digit code system known as ICD9.
