Yes, you can have two or more life insurance policies.
Life insurance companies understand that over time your need for life insurance may grow as your financial responsibilities increase throughout your lifetime.
For instance, you may own a small life insurance policy and then get married and start a family.
Your need for additional life insurance grows quite a bit once you have a spouse and children because you have others who rely on your income to provide for their home, clothing, food, living expenses, etc.
Insurance companies don't want you to be over-insured, but they are alright with you owning more than one life insurance policy.
