It won't store leading zeros, however. This may or may not be an issue
for you.


test=# create table tel (name_id integer not null, tel_numeric
numeric(15) not null, tel_varchar varchar(15) not null);
CREATE TABLE
test=# insert into tel (name_id, tel_numeric, tel_varchar) values
(1,012345678911234, '012345678911234');
INSERT 17153 1
test=# select * from tel;
  name_id |  tel_numeric   |   tel_varchar
---------+----------------+-----------------
        1 | 12345678911234 | 012345678911234
(1 row)

I would do as another poster suggested: create a telephone number
domain as text with the check constraints you desire.
