Relational database or what? :-)

Cannot you simply follow your algorithm? You just need to permanently store (for instance via serialization) the last generated suffix.

Fair enough, a 5, but I would rather keep the unique ID a totally abstract number, leaving the year, school code and other sentimental detail for student profile info. Duplicating any data is a sin. With a relational database, it would be enough to have a primary key of the integer type big enough to enumerate all students in a world. Staying away from all kinds of "school IDs" is good to avoid compromising future flexibility.

Check a method just pass the parameter year, bla bla and get STUDENTID

string GetObjectID(int sequence, string yr = "14", string d = "02")
  {
      string getZero = "";
      for (int i = 0; i < 5 - sequence.ToString().Length; i++)
      {
          getZero += "0";
      }
      return yr + d + getZero + sequence;
  }

This will return like
for 1 : 140200001
For 10: 140200010
For 99: 140200099
.....
for 999: 140200999
