### Question
Provide the zip codes and CBSA officers of the postal point in Oxford.

### Hint
CBSA officers refer to CBSA_name; postal point refers to zip_code; Oxford is the city;

### SQL
SELECT T2.zip_code, T1.CBSA_name FROM CBSA AS T1 INNER JOIN zip_data AS T2 ON T1.CBSA = T2.CBSA WHERE T2.city = 'Oxford'
