The questions, one by one
Can I let my house in Spain without a registration number?
No. And the number must appear in the listing, not merely exist.
It is the question that arrives in June, once the listing is already up. It is worth asking in March.

Holding it is not enough: it has to be visible
The registration number must appear in all advertising and all offers. A listing without a visible number does not comply, even if the registration exists and is up to date.
In the Valencia region, advertising a holiday home without its registration number is a serious offence (Law 15/2018, art. 92.16), fined from 10,001 to 100,000 euros (art. 94). Letting it without having filed the declaración responsable is a very serious offence: from 100,001 to 600,000 euros (art. 93.1).
And it does not excuse you from filing
Holding the number settles the tourism side, not the tax side. Rent received is declared regardless, and if you do not live in Spain it is declared on the modelo 210. Two different administrations, and complying with one does not excuse the other.
