PO Box & multiple LLCs

[Brandon R.]

I have a few LLCs. Each fully owns a single family house. 

I just got a PO Box for a non real estate LLC. Can/should I share this PO Box for the mailing address for all my LLCs? Would this contribute to Piercing the Corporate Veil?

I already have registered agents for the official mailing addresses. This new LLC needed a mailing address for normal mailing activities (I’ve always understood that the registered agent address is only for legal mailings vs ‘normal’ business mail).

thanks!
