What kind of mortar is it?

It's time to repoint joints between bricks and fix some cracked mortar.
I'd like to find the same or close type of mortar.
HD employees do not seem to know what kind of mortar it can be.

House was built in 1964 and on my street there are a few houses with the same type of mortar.

Do anybody know what could it be and where to buy it?

Matching old mortar is an art. Several things work against you: First, it was often mixed on site using cement, lime, and sand rather than buying a commercial sack mix. Sand was usually obtained locally and there is tremendous variation in color and texture. Second, the appearance of mortar changes as it ages and weathers, so even if you had the exact material used originally, it wouldn't match now. Third, the proportions of the ingredients are varied to make different strength mortars, and this changes the appearance too.

If you really want it to match, the best advice I can offer is to find an experienced local mason who does a lot of tuck-pointing and is willing to experiment to find a decent match. He can even add a bit of colorant if necessary, but step one is going to be finding sand that is a close match. In your pictures the sand is quite prominent so matching that will be important. The chance of buying a sack mix that even comes close is remote.
