Search this question and nearly every result is published by a domain registrar or a hosting company. That does not make them wrong, but it does mean the answer is usually "register both", which is the answer most likely to sell two things.
This website runs on a .com.np. I chose it deliberately, I have lived with it for a while, and there are things about it I would tell someone before they copy the decision.
The short answer
If your customers are in Nepal and will stay in Nepal, .com.np is fine and free. If you sell outside Nepal, or you might, buy the .com. If you are not sure, buy the .com — it is a few hundred rupees a year to keep an option open, and it is the only part of this decision that is genuinely hard to reverse.
Everything below is why.
What the country code actually does for ranking
A country-code domain like .com.np carries a built-in geographic signal. Google treats it as targeted at Nepal, and you cannot change that in Search Console — the setting is greyed out, because the domain has already answered the question.
That is a genuine advantage for searches inside Nepal and a genuine limitation outside it. It is also a smaller effect than the registrars imply. Geographic relevance is one signal among many, and it will not lift a slow, thin site above a fast, well-structured competitor. I have never seen a domain extension decide a competitive result. I have often seen it break a tie.
A .com is geographically neutral, which means you can target Nepal explicitly through Search Console, your content, your address, and your Business Profile. Slightly more work, no ceiling.
What free actually costs
.com.np registration is free through Mercantile, which is a real and unusual advantage. There is no renewal fee. For a small business that matters.
The trade-off is administrative rather than technical. Registration requires documentation, approval is manual, and it is not instant — it is a process rather than a checkout. Transfers and changes run through the same process. If you have ever needed to move a domain quickly, you will understand why that is worth knowing in advance rather than during an emergency.
There is also a subtler cost. Free registration means the namespace has been extensively claimed, and the name you want is more likely to be taken by something dormant.
The trust question cuts both ways
Registrar articles usually claim .com.np signals local credibility. That is true, and it is more true than it sounds — inside Nepal a .com.np reads as an actual registered entity rather than something set up in an afternoon.
The reverse is also true and gets mentioned less. To a customer in Australia or the US, an unfamiliar country-code extension is a small, unquantifiable hesitation at exactly the moment you are asking for a card number. That hesitation is worth more than the ranking signal if any meaningful share of your revenue comes from outside Nepal.
Trekking companies, export businesses, software firms and anyone invoicing internationally should weigh this seriously. A restaurant in Koteshwor should not.
The practical annoyances nobody mentions
These are the ones I only learned by running one.
Length. .com.np is seven characters. On a business card, in a WhatsApp message, read aloud on the phone — it is longer than people expect and it gets mistyped.
Some forms reject it. Not many, but some third-party services still validate domains against an outdated list and will not accept a two-level country domain. You discover this at the point of signing up for something.
People assume the .com. Whatever you put on the sign, a proportion of visitors will type .com. If somebody else owns that, you have handed them warm traffic. This is the strongest practical argument for buying both, and it has nothing to do with SEO.
If you register both
Pick one as canonical and redirect the other to it with a 301. Do not run the same site on two domains — that is two addresses for one thing, and it splits every signal you have.
Which one should be canonical depends on the audience, not on which you like. Nepal-only: .com.np. Mixed or international: .com. Then redirect, set canonical tags to the chosen domain, and make sure internal links point at it rather than the redirect. Redirect chains and mixed internal links are among the technical problems I keep finding in audits.
If you are changing an existing domain
Then this stops being a domain question and becomes a migration question, which is a different and riskier piece of work. Traffic lost in a domain change is almost never lost because the new domain is worse — it is lost because a few hundred old URLs stopped resolving and nobody made the list before the old site went away. The order to do it in is here.
If the current domain is established, has links and ranks for things, the bar for moving is high. "I would prefer a .com" is not a sufficient reason. "We now sell to three countries and the country code is costing us conversions" is.
What I would tell a client in one sentence
The domain extension is one of the least important decisions you will make about your website and one of the most expensive to change later, so spend ten minutes on it, buy the .com if there is any chance you will need it, and then go and spend the rest of the week on the things that actually decide whether you rank — which are speed, structure, and whether the pages answer what people typed.
If you are about to build or move a site and want the domain, redirect and canonical decisions checked before rather than after, that is part of what I do.
