([royalmail.com](https://www.royalmail.com/receiving/delivery-times?utm_source=openai))\n\nHowever, there *are* specific Sunday delivery services for certain parcels and premium mailing options:\n\n- **Tracked 24\u00ae** and **Special Delivery Guaranteed** both offer parcel deliveries on Sundays, but only in selected areas. These services need to be arranged via a business account. ([royalmail.com](https://www.royalmail.com/business/shipping/uk-services/sunday-parcel-deliveries?utm_source=openai))  \n- If you purchase *Special Delivery Guaranteed*, even letters under that service may be delivered on Sunday in locations where Sunday delivery is available. ([royalmail.com](https://www.royalmail.com/business/shipping/uk-services/sunday-parcel-deliveries?utm_source=openai))  \n\nThere are also **postcode exclusions**: some areas are not eligible for Sunday delivery under these services. You can check whether your postcode is excluded via Royal Mail\u2019s \"Sunday Delivery Postcodes\" resource. ([royalmail.com](https://www.royalmail.com/termschanges?utm_source=openai))\n\nIf you tell me your postcode, I can check whether Sunday delivery is available in your area."
