You could use 64-bit integers (which can store numbers as high as 9,223,372,036,854,775,807), as described here . 你可以使用64位整数（可存储数高达9,223,372,036,854,775,807），如所描述这里 。
However, I think that phone numbers are better stored as strings than integers, since you may need to represent leading zeroes. 但是，我认为电话号码最好存储为字符串而不是整数，因为您可能需要表示前导零。
