How do I know if this lady Ayishatu Zido passport is real the number is
H 1299986

Does she live in Ghana?

You can't know if the passport is real.

You can know if you're being scammed. Is she asking for money? Is she telling you she loves you, wants to marry you, just wants to meet you, so send her money so she can?

No two passports can have the same number. I been emailing a supposed to be lady for over 2 years. I found 2 days ago that another 2 persons has this same passport number. I had sent some money during that time frame, but not much. Due to that I kept asking for this person to do a web cam, and did not. Then I asked this person to send newer photo's and she had not.
After realizing and finding that 2 other persons had the same passport number, I realized that this person can not sent new photo's probably because either he or she set-up the original person who posed for the passport photo, the person realized they were being used and walked away, or maybe something more worst?
It could be that all 3 to include your lady wanted to be for real, but they all went to the wrong person to get passports made and from then on, who knows? Other than the fact that I have stated here in. My lady had the passport number of H1299986 along with 2 other persons.
I used to be married to a South Korean girl years ago. So I know about these things.
Always run a check on persons in Ghana and countries like that.
