17,352 PointsQuestion on Integer data type
Can integer data types work for numbers when there is a 0 prefix? For instance, a five digit zip code such as 07210. A social security number and bank account# are other examples.
For instance, we don't want a 07210 zip code to display as 7210. Or a customer with bank account # 00012345 may not be the same as one with 0012345 or 12345
