Sort out the most unique data

[doharr]

Have DATA in one column:
1487 replaces 1487P
1508 replaces 1508P
1518 replaces 2809, 47-7900, 703247
1518 replaces 47-7900, 703247
1518 replaces 703247
1521 replaces 1521P
1528 replaces 208173, 252-88, 47-9600, 705478
1528 replaces 252-88, 47-9600, 705478
1528 replaces 47-9600, 705478
1528 replaces 705478
1535 replaces 1535P
3715 replaces 3139, 5234, 7582, 7585
3715 replaces 5234, 7582, 7585

Only want to keep the most unique data:
1487 replaces 1487P
1508 replaces 1508P
1518 replaces 2809, 47-7900, 703247
1521 replaces 1521P
1528 replaces 208173, 252-88, 47-9600, 705478
1535 replaces 1535P
3715 replaces 3139, 5234, 7582, 7585

Need help on a VBA code to sort out the most unique data.
Thank you in advance for any help.

The way your sample data is presented, you seem to just want each row where the number at the start changes. So, assuming...

1. Data is in column A, starting in row 2 (allowing for heading in row 1)

2. Columns B and C are vacant

3. All the leading numbers are 4 digits.

4. You just want the first occurrance of each 4 digit number

... then try this. If any of my assumptions are incorrect or this doesn't do what you want for some reason, then please provide more details.
